There hasnt been any mention of Collosus or Storm, so I wouldnt be suprised if those roles ended up going to Iceman and Rogue, who are working with Wolverine. Movie Wolv & Rogue have a special bond. I wouldnt be suprised to see Rogue taking over the Collosus role of the story. Giving her the super strength fans were clamoring for previously and it serves a purpose storywise to have a strength character when dealing with giant robots.

Good point conan69. I think it would make sense for Rogue to fill in for Colossus and for Iceman to fill in for Storm because their powers are similar to each other in the comics. Hey this could be why Anna Paquin signed on right away. I heard she was almost not in X3 because she tried to get out of it by starring in a movie that coincided with X3's shooting schedule. If she's not going to work on another project that will coincide with DOFP that must mean she's pleased with Rogue's treatment this time.
